父類調用子類的常量 lumen查詢數據庫方式

我要在一個基類裏面實例化全部的model 要根據集成的對象定義的model實例化

 

BaseRepository.php

<?php

namespace App\Repository;

class BaseRepository
{


    //獲取到model的對象 相似於再倉儲裏面直接  User::get()
    public function query()
    {
        $model = static::MODEL; //經過這個能夠調用到子類定義的MODEL常量
        return new $model();
    }

}

 

UserRepository.php 

<?php

namespace App\Repository;

//倉儲 用於鏈接service和model
use App\Model\User;
use Illuminate\Support\Facades\DB;

class UserRepository extends BaseRepository
{
	const MODEL = User::class;

	public function getUserList()
	{

		$res = (new User())->first();  //new對象後查詢
		$res = User::first(); //直接靜態調用查詢

		$query = $this->query(); //調用基類返回對象後查詢
		return $res;
	}
}
